The best way to live a life based in truth, and the best way to be of use to the world, is to expand consciousness both inwardly and outwardly. Deeply investigate your own consciousness, divest yourself of the misperceptions and erroneous assumptions around thought, perceiving and selfhood which are driving your behavior, and discover your true nature. Also, learn everything you can about what's going on in the world, how people are being subjected to needless suffering by abusive systems, how power is really structured, what the mechanics of our civilization's dysfunctions are, and where some possible solutions might lie. Do both of these things.
